Functional Descriptions

Counter Mode

Up-Counting

The counter counts continuously from 0 to the counter-reload value, which is defined in the

CRR register. Once the counter reaches the counter-reload value, the Timer Module generates an overflow event and the counter restarts to count once again from 0. This action will continue repeatedly. When the update event is generated by setting the UEVG bit in the EVGR register to 1, the counter value will also be initialized to 0.
